getfiles () is part of the advanced option parsing interface together with the getargs () and getallrgs () family. getfiles () skips options until a file type argument is encountered.
getfiles () returns, with a value of "+1 " ( NOTAFLAG ) or "+2 " ( FLAGDELIM ), whenever a non-flag type argument is encountered. Flag-type (option) arguments, along with their values, are ignored. The filename is at *pav[0] . The caller must increment *pav and decrement *pac before calling getfiles () again.
getlfiles () is similar to getfiles () but it implements an additional ga_props parameter that must be initialized with getarginit () before it is passed.
getvfiles () is similar to getlfiles () but uses a structure ga_flags instead of a format string and a variable arg list with pointers. The array of structures ga_flags :
struct ga_flags {
const char *ga_format; /* Comma separated list for one flag */
void *ga_arg; /* Ptr. to variable to fill for flag */
getpargfun ga_funcp; /* Ptr. for function to call (&/~) */
};
is terminated by an element with
"ga_format == NULL" . For a
ga_format that does not expect a function pointer,
ga_funcp is
NULL . 14 FLAGDELIM 2 The command line argument "\c --\c " stopped flag processing.
NOTAFLAG 1 The argument *pav does not appear to be a flag.
NOARGS 0 All arguments have been successfully examined.
BADFLAG -1 A bad flag (option) argument was supplied to the program. The argument *pav contains the offending command line argument.
BADFMT -2 A bad format descriptor string has been detected. This means an error in the calling program, not a user input data error.
NOTAFILE -3 A flag type argument rather than a file type argument has been detected. ..
General rules for the return code:
14 > 0 A file type argument was found.
0 All arguments have been parsed.
< 0 An error occured or not a file type argument.
Flag and file arg processing should be terminated after getting a return code <= 0.
